Assessing exactly the influence of heater terminal temperature difference on turbine power is significant meaning for the design, operation and repair of thermodynamic system. The method adopted is based on heat balance equation and turbine power equation of thermodynamic system. Take the partial derivative of outlet water enthalpy on both sides of the above equations, the law of the formulas can be found. So, for different heater type, the general calculation model on the influence of heater terminal temperature difference on turbine power is derived in the paper. One important conception, which is called as terminal temperature difference equivalent enthalpy drops, is defined in the paper. The model discussed in the paper is proved to be possessed of the character of accurate, simple and more universal. Especially, it is suitable for on-line monitoring system of unit heat economy.
